rated only by the tendon of the hock running between them, which 
indeed was almost effaced by their protuberance on each side of it. 
The diagnosis pronounced was, that the swelling was caused by 
tumefaction of the tarsal theca, having no communication with the 
capsule of the hock joint. 
The prognostic was serious. In such a state of enlargement as 
this is, tendinous sheaths too often resist every means of reduc- 
tion ; and, since the hock has been twice fired, and once simply 
punctured, nothing seems to remain to be tried but the iodine. 
Notwithstanding the uncertainty of such treatment, and the danger 
with which it is on occasions attended, still here is an extreme 
case, and one in which, even should we fail in the experiment, we 
should not be compromising any hopes on the part of the owner. 
Treatment. — Accordingly, on the 4th of August, the patient 
being cast, and the limb to be operated on properly positioned, and 
an injection being prepared, composed of one part of tincture of 
iodine and three parts of water, at nine o’clock, A.M., the operation 
was commenced by plunging a trocar into the more dependent part 
of the tumour, the withdrawal of the stillet of which was followed 
by a copious issue of limpid synovia, manipulation being used to 
both tumours to press out their contents, and afterwards three 
ordinary syringes-full of the iodine mixture were injected. This 
quantity proved barely sufficient to give the sheath its former dis- 
tention. After suffering it to remain in three minutes, the injec- 
tion was allowed to escape, and was got rid of as completely as 
possible by pressure with the fingers. 
The. horse was then suffered to rise, and he walked to his 
stable nowise lamer than before. 
At eleven o’clock he was found easing the affected limb. And 
the two tumours, flaccid as they were after the operation, have 
now become hot and tender. 
At one o’clock, P.M., pain and lameness had increased in the 
limb, and the tension and heat in the swellings had become 
extreme. Still no very sensible fever. 
At one o’clock, P.M., slight fever of re-action, marked by some 
respiratory disturbance, and tension and hardness of pulse. Let 
blood from the jugular. 
Aug. 5th . — The pupil on duty reports that nothing particular 
occurred during the night. The horse lay pretty uninterruptedly. 
At half-past six o’clock, A.M., the circulation and respiration 
had regained their normal beat. Still verj' lame at walking ex- 
ercise. Tumours hot and tense, as overnight, though less sensitive. 
6th . — Lameness diminished. Tumours as yesterday — no fever. 
1th . — Rests firmlv upon the affected limb.
